Heat elements positioning

Hi all,

Does anyone know if the heat elements in a vertical heat treatment kiln
can be placed upright (vertically).



Most of the vertical kilns that I find photos have the resistances
mounted horizontally. Why?

Yes, you "CAN" place elements that way, but that doesn't mean you SHOULD. If you place heating elements in that manner, you will have "hot" and "cold" spots/areas in the kiln, and very inconsistent heating/operation.

When you say "resistances", I will assume you are speaking of the Heating Elements? If so, the reason you see them mounted that way is simple. In this situation, and most others, heat always travels up. In a vertical kiln placing the heating elements horizontally, ensures a much more even heating than if the elements were place vertically.
